Leviticus 23 vs Numbers 28
Question
I have been studying the Pentateuch, specifically to try to create my own chart of the feasts and offerings using the NKJB. I have a question: while studying Leviticus 23:15-22 and Numbers 28:26-31, I noticed a discrepency between the numbers of the sacrifices. This leads me to think 1) it is a copiest error, or 2) these are two different sacrifices. My friend, a former pastor, believes that these "first fruits" offerings occur before and after the Sabbaths of the Passover/Unleavened Bread week. If this is true, it seems rather arbitrary as to what happens when. So, I wanted to ask an expert. Could you please clarify these passages for me?
